CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 742,798, dat d October27,

Application filed August 28, 1903. Serial No. 171,126. (No model.)

To all whom it may concern:

Be it known that I, CORNELIUS P. MORAN, a citizen of the United States,residing at Gallitzin, in the county of Gambria and State ofPennsylvania, have invented a new and useful Oar-Brake, of which thefollowing is a specification.

This invention relates to the brakes of railway-cars, more particularlythe hand-operated brakes of freight-cars of various kinds, some forms ofmining-cars, and some forms of specially-constructed cars; but while thedevice is more specifically adapted for freightcars of various kinds Ido not wish to be limited in any manner in the use of the device form orstructure of car or to any specific form or structure of brake mechism,but reserve the right to its use upon any form of car or in connectionwith any of the various brake mechanisms in common use or to bespecifically constructed therefor.

The object of the invention is to simplify which it appertains; and tothis end the invention consists in certain novel features ofconstruction, as hereinafter shown and described, and specified in theclaims.

In the drawings illustrative of the invention, in which correspondingparts are denoted by like designating characters, Figure 1 is a sideview, and Fig. 2 is a front view, of the device applied. Fig. 3 is asectional view on the line 3 3 of Fig. 1. Fig. iis a perspective view ofthe operating-lever detached.

This invention may be applied to any of the various forms offreight-cars and to any of the various forms and constructions of brakesand brake mechanisms; but as these form no part of the present inventionthey are not illustrated in the drawings, sections only of a car-bodybeing indicated at to illustrate the application of the device, thesections represented indicating the upper and lower corners of thecar-frame, respectively.

The improved device consists of a supporting-frame, preferably pressedor otherwise formed of a single piece of steel, with parallel sides 1112, spaced apart and connected to the car-body, as by bolts 13 andspacer-tubes 1 1 or by any other suitable connecting means. The sideportions 11 12 are provided with alined bearings 15 16, in which an axleor shaft 17 is journaled, and carrying a drum or Windlass 18 andratchet-wheel19 between the frame members and a toothed wheel 20 outsidethe outer frame member 12, as shown, the parts 18, 19, and 20 being allconnected rigidly to the shaft 17 and partaking of its motion. A pawl ordog 21 is pivoted at 22 to the frame member 12 and operates against theratchet-wheel 19 to hold it from turning in one direction, while leavingit free to rotate in the opposite direction.

At the lower side of the car-body 10, in vertical alinement with theside of the Windlass opposite from the pawl 21, is a chain-carrier orguide-pulley 23, so that the brake-operatthe Windlass will'lead over theguide-pulley and thence to the brakeoperating mechanism, the latter notbeing shown, as it forms no part of the present invention.

To provide for the passage of the chain, the frame'll 12 is providedwith an opening 25, as shown, and to this end the frame is offsetlaterally, as shown at 26, to bring the opening 25 beneath the windingside of the windlass, as shown in Figs. 2 and 3.

Outside the frame member 12 the axle 17 is provided with anoperating-lever 27, forked at one end, as at 28 29, embracing theopposite sides of the toothed wheel 20, and the forked portions providedwith elongated apertures 30 31, engaging the axle, as shown. Theapertures are formed with intermediate inwardly-projecting lugs 32 33,as shown, whereby spaced recesses 34. are formed in the ends of theapertures, as shown. The forked portions 2829 are connected below theapertures by a pin 36, so located that when the lever is set with thelugs 32 33 upon one side of the axle 17 or with the latter in the recess35 the pin will engage one of the teeth of the wheel 20 and bedisengaged therefrom when the lever is set with the lugs upon theopposite side of the axle or in the recess 34.. By this arrangement whenthe lever 27 is moved longitudinally toward the toothed wheel the pin 36will engage one of the teeth of the wheel and with the axle 17 in therecess 35, and then when the leveris actuated in the direction of thearrow the recess and axle coact and become the fulcrum of the lever andmaintain the requisite connection between the parts to cause the pin 36to retain its connection with the wheel during the forward stroke. Inthe meantime, it will be obvious, the pawl 21 has by its action on theratchet-wheel retained the Windlass in position and prevented backwardmovement thereto, so that when the lever is released at the end of thestroke and permitted to drop with the axle in the recess 34 the Windlasswill retain its windings. The lever can now be returned to its formerposition, as the pin 36 is free from the wheel-teeth, and the strokerepeated as often as required.

The outer sides of the lugs 32 33, it will be noted, are inclined,whereby the movement of the lever 27 when about to be engaged with thetoothed wheel is less obstructed and whereby the action is rendered morecertain.

hen required, the axle 17 maybe partially released by moving it forwardslightly until the pawl 21 can be disconnected and the windlasspermitted to slowly rotate backwardly as far as required by holding backon the lever. By this simple means the brake mechanism may be quicklyapplied and with increased force, as the lever 27 may be of any requiredlength and strength.

The parts can be very cheaply constructed, easily applied to any form ofcar, and will be found very useful and convenient for the purposesdesignated.

Having thus described my invention, What I claim is 2. A brake mechanismcomprising a supporting-frame having spaced sides, an axle mounted forrotation through said frame and carrying a Windlass and ratchet-wheelbetween said spaced side portions and a toothed porting-frame havingspaced mounted for rotation waves wheel exteriorl of said side portions,a pawl carried by said frame and engaging said ratchet-wheel, and alever formed with an elongated aperture and provided with anintermediate lug and engaging said axle and having a lateral pin adaptedfor engagement with the teeth of said Wheel when said lever is set withsaid lug upon one side of the axle, and disengaged therefrom when thelever is set with said lug upon the opposite side of said axle,substantially as described.

3. A brake mechanism comprising a supsides, an axle through said frameand carrying a Windlass and ratchet-wheel between said side portions anda toothed Wheel exteriorly of said side portions, a pawl carried by saidframe and engaging said ratchet- Wheel, and a lever forked at one endembracing said toothed wheel, said tions formed with elongated aperturesprovided with intermediate lugs and engaging said axle upon oppositesides of said toothed wheel, and a pin disposed transversely throughsaid forked portions and adapted for engagement with the teeth of saidwheel when said lever is set with said lug upon one side of said axleand disengaged therefrom when said lever is set with said lug upon theother side of said axle, substantially as described.

4. A brake mechanism comprising a supporting-frame having spaced sidesformed with an intermediate lateral offset, an axle mounted for rotationthrough said frame members above said offset and carrying a Windlassbetween said 'framemembers and likewise carrying a ratchet-wheel andtoothed wheel, a pawl carried by said frame and engaging saidratchet-wheel, and an operating lever connected to be alternatelyconnected with and disconnected from said toothed wheel, the portion ofsaid frame below said offset being provided with an aperture in verticalalinement with the Winding side of said Windlass, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses.

CORNELIUS P. MORAN.
